Abstract

A manhole drop system is described which is convenient to inspect. A catch bowl made of an integral structure is formed to capture and channel sewer fluid entering a manhole an elevation that is above a bottom located sewer line. The catch bowl has its upper portion shaped to reveal both a lower exit port leading to down drain and to reveal the discharge opening from a side feed. The catch bowl has a front surface that is curved sufficiently to enable a relatively secure seal between the front surface and a curved wall of the manhole.
